TECHNICAL FIELD

The present application relates to the technical field of toys, inparticular to a bubble toy capable of blowing different sized bubbles.

BACKGROUND

The traditional bubble toy is very simple, and usually requires users toblow bubbles with their mouth. It is inconvenient to play, the playingmethods are not diverse, the amount of bubbles is small, and theinterestingness is not enough.

With the development of technology, the traditional way of blowingbubbles by mouth has been transformed into electric bubble blowing.Electric bubble toys can blow more bubbles and greatly increase theinterestingness, can bring joy to children and are conducive to thedevelopment of children’s intelligence. For example, one prior artdisclosed a toy bubble gun, which includes a shell, a liquid storagetank that can hold bubble liquid, a bubble discharge gun head providedin the shell, a liquid conveyor that can convey bubble liquid to thebubble discharge gun head, a blower that can blow air to the bubbledischarge gun head, a motor that drives the liquid conveyor and theblower, and a film former that can form a bubble liquid film at thebubble discharge gun head, wherein the blower includes a housing, animpeller provided in the housing and connected with one end of a motorrotating shaft, and an air supply duct connected with the housing andleading to the bubble discharge gun head. Although the toy bubble guncan automatically and continuously blow many bubbles, the size of thebubbles it blows is relatively monotonous (generally all small bubblesor all large bubbles), there is only one way to play with bubbles, themonotonous playing way cannot meet the demand of children for playingand innovation.

SUMMARY

One technical problem to be solved by the present application is toprovide a bubble toy capable of blowing different sized bubbles. Thebubble toy can automatically and continuously blow many bubbles, and thesize of the blown bubbles can be conveniently adjusted to meet thedemand of children for playing and innovation, thus helping to inspirechildren’s intelligence. The following technical solution is adopted: abubble toy capable of blowing different sized bubbles, including: ashell; a liquid storage bottle mounted on the shell; a bubbler mountedon the shell; a liquid conveyor that is mounted on the shell and conveysbubble solution from the liquid storage bottle to the bubbler; a blowerthat is mounted on the shell and provides airflow to a bubble outlet ofthe bubbler; a motor that is mounted on the shell and drives both theblower and the liquid conveyor; a power supply that is mounted on theshell and provides power to the motor; a switch provided between thepower supply and the motor; wherein the bubble toy also includes amovable baffle and a position adjuster capable of adjusting a positionof the movable baffle, the position adjuster is mounted on the shell,and the movable baffle is disposed at a front side of the bubble outletof the bubbler and is matched with the bubble outlet.

When the bubble toy is used, the switch can be turned on to supply powerto the motor, and the motor drives the blower and the liquid conveyor.At this time, the liquid conveyor conveys the bubble liquid in theliquid storage bottle to the bubbler, which forms a bubble film at thebubble outlet of the bubbler, and the blower supplies air to the bubblerto cause the bubble film to form bubbles, so as to realize automatic andcontinuous blowing of many bubbles. The user can adjust the position ofthe movable baffle through the position adjuster, change the area of thebubble outlet shielded by the movable baffle, and conveniently adjustthe size of the blown bubbles, so as to blow both large bubbles andsmall bubbles. In this way, the user can produce different sized bubblesaccording to his ideas, and the interestingness is stronger to meet thedemand of children for playing and innovation, thus helping to inspirechildren’s intelligence.
